I've been interested in Warren Thomas knives recently. Enough to purchase the Beretta Avenger.

It is an excellent knife as far as F&F and lock engagement. I can only imagine what a full WT knife would be like. What I want to know is how the CF (or G10 on the customs) is bonded to the metal and how strong that bond is. Also, how is the carbide bonded to the Ti blade? (silver solder?) Finally, how is the carbide edge when it comes to edge holding? Can it pop hair? Can it be sharpened... or is that irrelevant?

Thanks
 
I'm not up to date on attaching CF or G10 to metal, but I believe that the carbide edge is welded onto the Ti. Regarding its sharpness, a carbide edge cuts more like a saw rather than a proper knife edge, if you look at it under a microscope you'll see a fair difference. I think I heard something about very accurate tearing rather than the usual clean cut you'd get with a knife blade. Not sure about the other questions though.
 
Have you thought of contacting Warren Thomas directly and asking him?
I would think that he would be the best source for that information.

Hammer welding I'll bet. Like explosion welding it causes the different metals to exchange molecules under extreme pressure, and essentially become one solid piece.
 
My guess is that the epoxy-carbon composite is adhesively bonded to the metal with epoxy adhesive. I think that there is more metal in the blade than just at the edge. If the metal were just glued onto the edge it would make what is known as a butt-joint, which is not a very strong adhesive joint design. I think the metal protrudes into at least some of the blade. That would make a lap joint, which is much stronger.

Epoxy bonds can be quite strong, though not on the order of just having a slab of metal.
